This is F., one of my students in the Science Illustration class I've been teaching for around two weeks now. I wanted to sketch the whole class, but I rapidly gave up, for I spent most of the three hours going from one person to another. It never ceases to amaze me how this work looks so different when seen from the student and teacher point of view: very relaxed and very busy. I've done it several times as one and the other, so I should know! I hope that soon I'll be able to post some of my students' work (I just need to remember to take the camera with me next time). They are just beginning, but they are already producing great work.
